The optimal pump for highly viscous, compacted and crumbly substances that have a tendency to bridge!

General

For highly viscous, compacted and crumbly substances that have a tendency to bridge, the NEMO® BP Progressing Cavity Pump is the optimal solution. The NEMO® BP can be used in nearly all branches of industry to provide continuous, pressure-stable, gentle and low-pulsation conveyance with dosing in proportion to rotation speed. The special features of this model include the patented, horizontally positioned feeding screw, the integrated bridge breaker and the enlarged rectangular hopper. Optimal feed into the conveying elements is guaranteed by means of the coupling rod with this feeding screw and the conical force-feed chamber. The bridge breaker prevents bridging and makes the mixing of aggregates possible. The hopper dimensions can be adjusted to the individual application case. The block construction of the NEMO® BP with flanged drive is particularly compact and economical.

Technique

StatorVulcanized into the tube with sealing on both sides in a variety of elastomers, plastics and metals. Stator inlet with hopper-shaped opening for improved feed of the product into the conveying chamber.

Drive ChainDrive and connecting shaft with a coupling rod with patented, horizontally positioned feeding screw for optimal feed into the conveying elements and two gimbal joints for the transmission of power from the drive to the rotor.

Shaft SealsStandard with single-acting, bi-directional, wear-resistant mechanical seal. Upon request, with single- or double-acting mechanical seals of varied designs and from various manufacturers, cartridge and special seals as well as packed glands.

Suction and Discharge HousingPump housing has integrated bridge breaker for the prevention of bridge building and for the mixing of aggregates (e.g. for conditioning of drained sludge), enlarged rectangular hopper and conical force-feed chamber as well as coupling rod with patented, horizontally positioned feeding screw for optimal feed to the conveying elements.The hopper dimensions can be adjusted to the individual application case.Flange and threaded connections in accordance with DIN and international standards. Materials in steel, chrome-nickel-steel rubberized; also special materials upon request.

Block ConstructionThe drive is flanged directly to the lantern of the pump, resulting in compact dimensions, low total weight, constant axial heights irrespective of the construction type and size of the drive, and ease of maintenance and serviceability as well as high efficiency.

NETZSCH M-Ovas® grinding systems can be used wherever it is essential that solid matter in fluids be broken down reliably to ensure the prevention of pipe clogging and damage to downstream equipment.

TORNADO® Industrial Rotary Lobe Pumps T2

The TORNADO® rotary lobe pump is a positive displacement pump. The pumping action is generated by the contra-rotation of two rotors within the pump chamber which are synchronised externally. The media enters the pump chamber through the inlet port and is carried around the chamber by the rotors to the outlet port where it is discharged.
